Vibration vs. Sliding
Vibration vs. Sliding is a skill on Pengi from Lesson 2: Molecular Scale (Solids & Liquids) in Amplify Science (California) Grade 7.
Key Concepts
In a solid , molecules are locked into a rigid, fixed pattern. They possess energy but can only vibrate in place, which explains why solids keep their shape.
In a liquid , molecules break free from this rigid grid. They remain close together but gain enough freedom to slide past one another. This molecular sliding allows the liquid to flow and conform to the shape of a container.
